It does have, however, a very pretty lady (Jacqueline Bisset) who can be
observed scantily, or at least wetly and therefore clingingly, clad on
every possible occasion. There is also some pretty underwater
photography and some pretty fair suspense as good guys and bad guys
thrash around on the ocean bottom looking for long-lost treasure of the
Spanish Main, which is all mixed up with some more recently misplaced
valuables morphine that the wicked ones want to turn into heroin.
